Part of cricket match finished (4)
I believe the answer is:
over
'finished' is the definition.
(similar in meaning)
'part of cricket match' is the wordplay.
'part' indicates taking the first letters.
'cricket match' becomes 'ver' (I am not sure about this - if you are sure you should believe this answer much more).
The initial letter of 'of' is 'o'.
'o'+'ver'='OVER'
Can you help me to learn more?
(Other definitions for over that I've seen before include "Bout of six bowls in cricket" , "Work out of hours" , "Half a dozen deliveries" , "Directly above" , "Division of play in cricket" .)
